WINDOW-SCREEN.

Specification of Letters Patent. Paflggntigd F910, 26, jILQjL@ Application filed August 24, 1917. Serial No. 187,934.

To all whom it may concern:

Be it known that 1, CHARLES W. HmonoLIrrE, a citizen of the United States, residing at Lawrence, countyof Essex, State of Massachusetts, have. invented an Improvement in Window-Screens, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to window screens 7 of a type adapted to be slidably positioned in a window frame.

In screens of this type the runners on the window frame usually extend only half-way up and, to insert and remove a screen, the

screen must be lifted until its channels are free from the runners. In this novel structure, there is provided a screen adapted to be used with runners which extend the vertical length of the window and is so constructed that'the screen may be removed at any point.

Theprincipal object of this invention is to provide a screen which may bereadily inserted and removed at any point along the vertical length of the window frame.

Other objects of the invention will more fully appear from the following description and the accompanying drawings and will be pointed out in'the annexed claims.

In the accompanying drawings there has been disclosed a structure designed to carrv out the objects of the invention, but it is to be understood that the invention is not to be confined to the exact features shown as various changes may be made within its reasonable scope. a

In the drawings: I

Figure l is a view in elevation of the outside of the screen as inserted in the window frame;

Fig. 2 is an enlarged, broken-out view of the screenon the line 2-2 of Fig. 1;

Fig. 3 is an enlarged view of the upper portion ofthe screen broken away.

The window frame 1 is of the usual corrstruction and has applied thereto a pair of runners 2 which preferably extend the vertical length of the window frame and along which the screen is adapted to slide. These runners are desirably formed of thin strips of angle iron and are secured to the inside of the window frame. In this selected embodiment, the screen is provided with a main wooden frame 3 which carriesthe wire netting 4. This netting is preferably stretched across the screen frame 3 and the perimetrical portions of the netting are secured to This auxiliary frame also functions to reinforce the window frame of the screen. It consists of uprights 5 and 6 and the top and bottom bars 7 and 8. These uprights and bars are preferably formed of thin metallic strips and are screwed to the sides and top and bottom, respectively, of the screen frame, the edge portions of the netting being held between the four metallic strips and the four members composing the wooden frame. The sides of the screen frame are positioned against the two outdoor faces of the runners. Each of these vertical frame sides is "preferably cutaway or planed down to an amount substantially equal to the thickness of a runner. There fore, when the surfaces of the cut away portions are sealed agamst the outer faces of V the runners a guiding or channel-forming upright 5 extends to the vertical edge of the wooden frame and thereby forms a vertical channel 9 in conjunction with the cutaway portion of the frame side which it overlies. This channel is adapted to receive one of the runners 2 of the wooden frame. The runner 2 has only such play therein as will permit the screen freely to be moved up and down. The other side of the screen is provided with a means movable on the frame to form guides normally to hold the frame on the runners but which can be moved out of position to permit the demounting of the screen. The metallic upright 6 on the opposite side of the screen frame is narrower than tends only to the vertical cutaway portion of the wooden screen frame at this side and does not overlie the'same so that a channel is not formed atthis side of the screen. The runner 2 at. this side is held slidably adjacent the cutaway portion of the screen by means of the novel movable guiding means.

This guiding means which engages the runners in cooperation with the cutaway portion of the upright 6 comprises preferably two members, one each at the topand bottom of the window screen. They are similar and but one is necessary to be described. Eachconsists of a guide Which *is pivotally'iiiount edto the screen frameand a is adapted to extend over the cutaway portion of the screen frame. Sufiicientspace is'left between theiguideand the cutaway poi-eon of" the screen to permit uiercepuen of the runner of the window fra'metherebeicured at one end as at 18 to the screen frame. is mount'ed so that,- when moved to normalg'uidingposition, ltSfittt face ISPI'BSQHE- tween. b v p v V This guide 1O may be formedof a narrow thin piece of'sheet metal andpivotally secd'in aplanesubstantiallyparallel to that of therun'ner, The u'pper and lower -guides thus functionto hold the screen frame in slidable position on'the'runner's. Whileboth "sides may be'providedwith the novel guiding fmeans, it is preferable'to provide a "perma- ".nent channel-0n one s'ide of the screen as the provision of the guldes on one s1de'1s sufficientto; permit the facile demou'n-tlng or re movalof the'screen. Whenit is desired to remove the screen from the Window frame,

the tvv 'guidesare'swung about their pivots 181un'til they are clear of the runners when the 'fscreen' is released and "may be j pulled f sidewise to remove the vertical'oha'nnel from the' otherrunner oft he Wmdowframe;

Means forglocking 'the'guide in normal This effected by a docking member pivotally movable mounted on the screen frame and adapted toffengageguide ;10 when the latter is in normal operative position. These locking membersare similar and 'one isprovided to lock each guide. 'jpreferablyiprovided with a flahge 11 which, when theguide is-in' normal position, is horiizontally seated upon the upper "surface of Each" guide is the topof the screen. frame and, in case of the lower" guide, is similarly seated against 7 the'lower' surface bf the bottom of the screen frame. The'locking member 12 in this se- 'lected embod ment, s made of a narrow piece 'of sheet metal and is pivotally'. mounted at 19 on. the screen at one'endi to's'wing in a path. substantially at a right angle to the path of movement of' the guide '10. When the "2 1 B :18 llQv d t0, operative piositibn; the

Pfffably ma'defof pieces of "small angle iron which thus providesithef guide 10 with at 'theend opposite the pivot in order to leavea thin t'ongue to engage the runner, ,wliile't'hejfiange remains onlthe major porftion' of the' g'uide inorder to afford :a "detent 1 surface for jtlie pivoted locking member. flTh npstan'ding-flange "13 of the locking ':;'Inember"12"oifers a convenient medium for an integral flange 11. The flange is cut away manipulating this device; Preferably, the

top and bottom metallic strips 7 and 8 of the auxiliary frame of the screen extend these holes maybe p'rojectedia pinor nail to bereceived in a hole 15 inthe upper portion of the window frame. Similarly opposed pairs of holes 16 are provided infthe runners within which may be inserted a similar device to permit the bottom of the screen frame to rest upon the projecting portion and thus to hold the screen 111 a=plurality' of elevated positions. In this -embodiment, the hole 15 is formedin a; strip 17 of'angle iron, one angular portion of Wl11Cl1 18 secured to the under face of the cross-bar forming the top of the usual wooden window frame. "When the screen is in uppermost position, the other dependm portion ofthe strip 17 functions to provide an insect tight closure at this portion of the window. frame.

As shown in Fig. 1, the strip. 17 is set inwardly from the plane of the two runners 2, Thus, in uppermost position of the screen frame, the top strip 7. of I the 'screen frame and theguide 10. Willbe positioned against or closely adjacent this ;.window frame strip 17 and form therewith an insecttight closure even when the window frame is warped or distorted in construction br in 7 service.

By the employment of this novel structure, the screen may bereadily inserted and removed and,furthermore, it may be somanipulated at any Verticalposition with relation to the window frame. This is-a. great convenience over the usual type'in which the runners extend :only part way on the window frame and the screen structure must be moved vertically until the usual channels. on

each side of the screen are free from the runners.

' Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: p

1.1 A window screen having a nettingjand a frame carrying the netting and adapted to be slidably mounted on runners in a window frame, means movable on said screen-frame to form guides normally to hold the frame onthe runners, a member on said sreen frame to lock the guidingmeans in normal position whereby when unlocked tl1e-':guide may be swung out of positionan d the screen demounted.

side to receive a runner and the other side ofthe frame having a surface adapted to slide over one face of the other runner, guides movably mounted on the screen frame at its top and bottom and adapted to be moved to engage the last mentioned runner on its face opposite the face engaged by said surfaces of the screen frame.

3. A window screen having a netting and a frame carrying the netting and adapted to be slidably mounted onrunners in a window frame, the screen frame having means at one side to receive a runner, a guide pivotally mounted on both the top and bottom of the screen frame on the side opposite said means, each of said guides being adapted to pivot in a plane parallel to that of the adjacent runner, and a locking member pivoted adjacent each guide and movable only in a plane at an angle to the path of the guide whereby the locking member may be positioned over a portion of the guide when in operative position and movement of the guide prevented.

4. A window screen having a netting and m in or thia patentmay be obtained for a frame carrying the netting and adapted to be slidably mounted on runners in a window frame, the screen frame having a channel at one side to receive a runner, a guide pivotally mounted on both the top and bottom of the screen frame on the side opposite said channel, each of said guides being adapted to pivot in a plane parallel to that of the adjacent runner, an integral flange on each a guide, and a locking member pivoted adjacent each guide and movable only in a plane at an angle to the path of the guide whereby, when the guide is in normal operative position, the locking member may be positioned over the flange of the guide and movement of the guide prevented.

5. A window frame, a transverse strip depending from the top transverse portion of the frame, a screen having a netting and a frame carrying the netting and adapted to be slidably mounted on runners in the window-frame, and means for holding the screen in uppermost position whereby the depending strip forms an insect-tight closure in conjunction with the screen frame.

In testimony whereof, I have signed my name to this specification,

CHARLES W. HINCHCLIFFE.
